100. You can further improve your fish- farming by growing only male tilapia in your ponds. Male tilapia grow bigger faster because without baby fish to feed, all the food that you put into your ponds will be eaten by the male fish.
101. If you decide to grow male fish, use fish that are at least 10 centimetres long so that you can harvest them sooner. A male fish of this length will be fully grown in three to four months.
102. If you have a nursery pond, you can get male fish from it. The drawing below shows you the difference between male and female tilapia.

103. If you do not have a nursery pond, you may be able to buy male fish from another fish farmer or from a fish culture station.
